It's been so long I've forgotten exactly. I ordered through Summit, around $237 or whatever they're advertising it for.

Make sure you paint them things orange. Don't want anybody knowing you're fooling around with the General's perfection. I think a performance report is needed for this long awaited product.

No. You can be assured that they are made in America. That is the one thing Edelbrock has going for it.

Lucky these aren't popular in the mainstream... otherwise mailorder whores would be selling them so cheap that the only ones making any money on the would be Vic himself...

(can you tell I'm in the industry? :rolleyes: I just sold a Performer intake and 600 carb for a SBC and made $12 on the combo. The shop I sold it to is making $18 and matching mailorder. We have 11% profit margin to split two ways... :doh Thank you edelbrock...) :bang

That's what Summit and Jegs have caused for the little guy. I guess it's called competition.
I stop stocking any product that is sold wholesale to Summit or Jegs.
Edelbrock has a whole lot of their work done in Mexico so don't toot their horn so loudly. In fact it would be better for the consumer if they imported from China, the price could be lowered.
Very important, don't bo so sure that they aren't already importing from Asia. I know oif a few very large companies that import from there ,do a little machining and assembly and claim it's "made in the USA"! That's a fact.
I would like to drop some names but some of these large companies could squash me like a little bug, so just be aware that it's being done, regularly.

On another note, these aluminum water pumps can be done in Asia very inexpensively, just as good of quality. I had already looked into it. Problem for me is I don't want to stock min 500 water pumps per engine type, but my cost would be around $65 ea alum, cast iron about $30ea.
Having min 500 alum water pumps in stock for 409/348 doesn't excite me.d

Got my initial edlebrock water pumps in today. I ordered 5 and got 3 shipped. Callled Atech Motor sports or Summitt and was informed that they are not stocking this item as a shelf part. You can order a water pump and it will be dropped shipped. They shipped out pre-ordered water pumps from all BO. Other 2 pumps coming direct from Edlebrock. FYI

Why would you want to pay Edelbrock double what it cost to polish? There's small polishing shops galore in your/our neighborhood. You can get that done for about $40-$60 in a few days.

Dave,here's a link to a photo of the insides of the Edelbrock pump,the seal and bearing & shaft assembly look just like the 409 rebuild kit :dunno As for the polishing I don't think they offer that,after my test I'm going to polish my pump with many hours of sanding before buffing.

Hi Jim,


Nice pump. Polished would sure look great.


Please correct me if I'm wrong,............ but doesn't polishing external engine parts actually assist with heat issues? :scratch

The opposite effect, less surface area to radiate heat but the difference is quite small and not an issue, at least for me.

I try to weigh the pros and cons, first by ordering a polished pump, if available, and not knowing what Edelbrock would charge if it was, job is done, no extra running around, no sorry I lost your part, sorry I ruined your part, sorry it didn't turn out as nice as I thought it would, or maybe not in this case, but getting someone elses part back that wasn't as nice as yours. Seen all of this happen, especially with early big chevy trim and Harley parts.

True, fortunately I use a polisher that is trouble free, or has been for the last couple of years. But I totally understand what you are saying. Plating shops are the ones notorious for those hassles.

I just drove the 57 from work about 10 miles,I drove speeds of 30 to 45 MPH.The temp was 81 deg and the 57 ran 160 degrees and the needle didn't move at stop lights.I'll still run the test between the 2 pumps in temps in the 90's on Sunday,but I don't think I'll see much change between the 2 pumps.I bought the Edelbrock pump for mostly the looks,I plan on polishing the pump after the test.I would like to see some test results from a member that bought the pump for cooling concerns instead of looks.

I saw Jim at US 131 Motorsports park in Martin MI Sunday (the more I see that 57 the more I fall in love with it :clap ). The day started in the 80s and progressed into the high 90s before it was over. Jim pulled into the pit and checked the temp of his "09". About a 170 degrees in 90 degree weather after idling from the main gate to where we were! Don't know how you do it Jim.

Dick,Thanks for the kind words,the trip home was also a cool ride,the 09 was running temps of 170 to 175 at 70mph on the e-way in 95 degree heat.in the city driving temps did'nt go over 175 deg.It was too hot to switch to the Edelbrock and road test,I'll do that the next hot day.The Edelbrock pump has it's work cut out to beat my stock pump :dunno

Jim,

Eastwood, and even Home Depot both sell capable and complete polishing kits! Add some elbow grease, and you get all the shine you desire!

After you get it back polished, I strongly recommend that you use the ZOOPS polish pad-tape and proctectant. The stuff actually works -- the aluminum resists oxydizing and staining so common to polished aluminum parts.

Be sure to update us with new pictues of it installed!!! By the way, did you encounter the backplate bolt clashing against the timing cover, like I did?

Eastwood sells a product called Diamond Clear, for bare metal surfaces. I painted my intake with it, after I polished it. I don't know how it'll stand up to daily hot/cold cycles on the engine, since my engine isn't running yet. I can honestly say, it didn't take anything away from the shine, after I sprayed it on. :clap Skip:)

Jim,

Actually, I just didn't feel ike polishing the Edelbrock water pump! As it is, there's plenty enough glitz on this engine to blind you! And, the pictures posted of it, do not give the engine jusitce, believe me!

As for the Lamar WP (actually Lamar had nothing to do with prodicing these WP's), I wanted something that cooled at least as good as a stock wwater-pump, that the so-called Lamar pump is not up to it. I will eventually rebuild it with proper inards...

Why do you want a press in by pass tube ?I like the 3/8 inch pipe plug.Why do you want to grind the name off pump ?Here's a photo of the back of the pump with the cover off,the impeller is made of precision cast powdered metal.

Why would you want a pressed in tube for the by-pass? That's just one of the reasons I refuse to buy the cast iron pump that Showcars sells, it has a pressed in by-pass tube. I don't run a by-pass, so I would be stuck with an ugly rubber nipple to plug that thing off. The original GM's did not press in a by-pass tube.

Easy Jim, I care. I have one and will be installing in a week or two. With the increased volume, I would assume you would have to run a thermostat. I run a Mr.Gasket hi-flow. Dropped 10 degrees by going with the Hi-flow stat. I run a 160 if memory serves.

Jim & Guys!

Here's a few more pics of my hydraulic-roller 446, with the EDELBROCK WP, painted! Jim, yours looks great polished, but if polished on my 446, there would be too much added glitz.

The pictures also show the chromed-steel pulleys -- 6" WP, and 7" Crank. I'm still several weeks off from firing it up, but -- it may never see the 55 Chevy's engine bay!

You see, my aluminum heads should be here next week (still getting the valve work), and so, I'll be building out my 3rd stroker using those heads, pronto. " :dunno

Enjoy the pictures!

Road test
(1) 95 deg--6"water pump pulley--no stat---180 to 200 deg
(2) 92 deg--6" water pump pulley--1"restrict or--175 to 200 deg
(3) 85 deg--6" water pump pulley--180 stat--190 to 210 deg
(4) 82 deg--7" water pump pulley--no stat--180 to 210 deg
(5) 83 deg--6" water pump pulley--no stat--160 to 190 deg

It looks like the 57 preforms better in 80 deg temps with the 6"water pump pulley.

Although the Edelbrock pump performs o.k. I am suprised it does not cool as well as a stock rebuild. Have you tried a 160 hi-flow stat? I finally got the rear together today and went for a ride. 80 or so today and it ran 170-185 hiway and in town with a stock pump. How much coolant do you run in your water. Remember, coolant impedes the cooling process. Run the minimum you can and cooling will increase. I will be installing the pump this coming week. I will be plugging off the bypass port. This I am told will help cooling slightly. Heater is also going I think. Will let you know what happens! :cheers

Jim,

From your above test results, I'm assuming you had the SAME belt-driven fan on all of the tests, yes?

In the testing above, (4) & (5), the improvement in cooling (if you used the fan), likely came from the faster rotation of the fan, and NOT because of a perceived increased coolant flow..., we demonstrated that last year, remember?

From (1) (2) & (3) above (using the same 6" WP-pulley ), it is clear that a 1" restrictor plate works better. Using a 180 thermostat, does not perfrom as well because no matter what temp-stat you use, it will somewhat block coolant flow, even when wide open. A 1" restrictor plate basically simulates a wide-open stat from moment one, but, without the added hardware what would block flow.

Also, to better compare your results, you need to define whether the car is running down the road or static in a garage, and the time and speed held if it is a true "road test", or the actual length of time the engine was running, if static in the garage.

If you really want to put a dead comparison of the Edelbrock WP to a stock pump, you need to test them at the same outside temperature (or inside garage temp), same 6" WP pulley and fan, and for the same time and speed held (or time running static in the garage).

As for a 5" WP pulley, my buddy runs one on his 383 dual quad gasser 55 chevy. He got it from March. I also have one, (billet aluminum) and although the pulley grooves are deeper, they do align with the crank pulley grooves. You may also need a spacer bushing because the WP pulley hole is larger (3/4") than the 5/8" WP shaft (I have one of them as well). I'll post a picture of it on my 446 if you like.

Remember too, if you do run a 7" Crank pulley with a 5" WP pulley, you'll be running some significant increases in WP RPM's..., but it'll surely pull a ton more air through the radiator!!

Jim,

From your above test results, I'm assuming you had the SAME belt-driven fan on all of the tests, yes?

In the testing above, (4) & (5), the improvement in cooling (if you used the fan), likely came from the faster rotation of the fan, and NOT because of a perceived increased coolant flow..., we demonstrated that last year, remember?

From (1) (2) & (3) above (using the same 6" WP-pulley ), it is clear that a 1" restrictor plate works better. Using a 180 thermostat, does not perfrom as well because no matter what temp-stat you use, it will somewhat block coolant flow, even when wide open. A 1" restrictor plate basically simulates a wide-open stat from moment one, but, without the added hardware what would block flow.

Also, to better compare your results, you need to define whether the car is running down the road or static in a garage, and the time and speed held if it is a true "road test", or the actual length of time the engine was running, if static in the garage.

If you really want to put a dead comparison of the Edelbrock WP to a stock pump, you need to test them at the same outside temperature (or inside garage temp), same 6" WP pulley and fan, and for the same time and speed held (or time running static in the garage).

As for a 5" WP pulley, my buddy runs one on his 383 dual quad gasser 55 chevy. He got it from March. I also have one, (billet aluminum) and although the pulley grooves are deeper, they do align with the crank pulley grooves. You may also need a spacer bushing because the WP pulley hole is larger (3/4") than the 5/8" WP shaft (I have one of them as well). I'll post a picture of it on my 446 if you like.

Remember too, if you do run a 7" Crank pulley with a 5" WP pulley, you'll be running some significant increases in WP RPM's..., but it'll surely pull a ton more air through the radiator!!

Denis,all tests were done on the same 13 mile route,I went through 4 different speed zones,25,35,45 and 55mph,I also let the 57 idle 5 min in the driveway.Do you know the part # on the 5 inch pulley ?

Yesterday I went to a car show and Cruise,the 5 1/4"Water Pump Pulley preformed Great and the Autolite Platinum spark plugs preformed Great on startup,idle and performance :) I ran 140 deg on the open road and 190 to 200 deg in bumper to bumper slow moving traffic.More Good news the 57 took a top 25 Award :D

Road test
(1) 95 deg--6"water pump pulley--no stat---180 to 200 deg
(2) 92 deg--6" water pump pulley--1"restrict or--175 to 200 deg
(3) 85 deg--6" water pump pulley--180 stat--190 to 210 deg
(4) 82 deg--7" water pump pulley--no stat--180 to 210 deg
(5) 83 deg--6" water pump pulley--no stat--160 to 190 deg
(6) 82 deg--5 1/4"water pump pulley no stat--140 to 190 deg

All this water pump/pulley diameter/fan & shroud size testing is a tremendous benefit for everyone. Beautiful work on those cars.

Something MAGIC about a 409 in a tri-five.

Jim,
Congratulations on the top 25 award.. the '57' deserved it for sure!

We really need to get all the FORUM tri-5 W's together one day!!!

I recevied my 2nd Edelbrock aluminum WP today -- from Summit. I ordered the thing eons ago... came in from their Nevada warehouse.

I'll be ordering the rest of the inards for my next 446 stroker, which will sport Bob Walla's aluminum heads, the Edel-WP, and a few other surprises to be announced later.

By the way, I rethought the throttle linkage for the M/T x-ram intake. Prior pictures I posted of my current 446 had the primary linkage on the driver's side carb, which worked fine but, left little room for error with the master cylinder and firewall. I went to a new billet Lokar back-bracket mounted on the passenger side carb -- much cleaner looking and more effective install. I'll post more pics of it soon.
